J., Fla., and Tex., near the coast.

Var. cleistogama, Gray. Only 1--2' high, bearing 1 or 2 evidently cleistogamous purplish flowers, not larger than a pin's head; capsule becoming 1” long. (The unnamed Utricularia in the Man., p. 320).--With the ordinary form; Barnstable and Nantucket, Ma.s.s., pine-barrens of N. J., and southward.

12. U. cornuta, Michx.

and Tex.; common.

2. PINGUiCULA, Tourn. b.u.t.tERWORT.

Upper lip of the calyx 3-cleft, the lower 2-cleft. Corolla with an open hairy or spotted palate, the lobes spreading.--Small and stemless perennials, growing on damp rocks, with 1-flowered scapes, and broad and entire leaves, all cl.u.s.tered at the root, soft-fleshy, mostly greasy to the touch (whence the name, from _pinguis_, fat).

1. P. Vulgaris, L. Leaves ovate or elliptical; scape and calyx a little p.u.b.escent; lips of the violet corolla very unequal, the tube funnel-form; spur straightish.--Wet rocks, northern N. Eng. and N. Y. to Minn., and far northward. (Eu., Asia.)

ORDER 78. BIGNONIaCEae. (BIGNONIA FAMILY.)

_Woody plants, monopetalous, didynamous or diandrous, with the ovary commonly 2-celled by the meeting of the two parietal placentae or of a projection from them, many-ovuled; fruit a dry capsule, the large flat winged seeds with a flat embryo and no alb.u.men, the broad and leaf-like cotyledons notched at both ends._--Calyx 2-lipped, 5-cleft, or entire.

Corolla tubular or bell-shaped, 5-lobed, somewhat irregular or 2-lipped, deciduous; the lower lobe largest. Stamens inserted on the corolla; the fifth or posterior one, and sometimes the shorter pair also, sterile or rudimentary; anthers of 2 diverging cells. Ovary free, bearing a long style, with a 2-lipped stigma.--Leaves compound or simple, opposite, rarely alternate. Flowers large and showy.--Chiefly a tropical family.

1. Bignonia. Pod flattened parallel with the part.i.tion. Leaves compound, tendril-bearing.

2. Tecoma. Pod flattish contrary to the part.i.tion. Leaves compound, without tendrils.
